Santa is planning on bringing me a D700 for Christmas. I already have a 70-300mm and he also planning on bringing me a 17-35mm 2.8. I would like to get a fast prime as an in between lens. I was thinking of either the 50mm 1.4G or the 85 1.4. I have been weighing the factors and I know the 85mm is way more expensive but every review I read seems to point to the 85mm as being an truly awesome lens. However at 85mm I have that range covered in my 70-300mm. Albeit, not at 1.4. I figure the 50mm fits in between the other two lenses. Everyone seems to like the 50mm but not as much as the 85mm! Owning both would be the ultimate way to go but way too expensive for now. So if I had to only get one prime should I get the 50mm or 85mm? I would like to use the prime to do indoor low light shots and portrait.
The other issue for me on this decision is I shoot with D90 with a DX sensor so I don't have the feel for whether the 50mm will be too wide for indoor shots of the kids etc.when I go full frame with D700.
I know the logical answer is the 24-70mm to fill in the gap, but for now I would like to just get a fast prime.
